The researches about gestural interfaces have been grown significantly. In particular, after the development of sensors that can accurately capture bodily movements. Consequently, several fields arise for the application of these technologies. Among them stands the 3D modeling industry, which is characterized by having robust software. However, these software often lack a facilitator human-computer interface. This happens since the interaction is usually enabled by 2 degrees of freedom mouse. Due to these limitations, common tasks such as rotate the scene viewpoint or move an object are hardly assimilated by users. This discomfort with the usual and complex 3D modeling software interface is one of the reasons that lead to quit its use. In this context, Natural User Interfaces stand out by exploring the natural human gestures in a better way, in order to promote a more intuitive interface. This work presents a system that allows the user to perform 3D modeling using poses and hand gestures, providing an interface with 3 degrees of freedom. An evaluation was conducted with 10 people, to validate the strategy and application proposed. In this evaluation the participants reported that the system has potential to become an innovative interface, despite its limitations. Overall, the hand tracking approach to 3D modeling seems to be promising and deserves further investigation.
